There is a lot of evidence of that. A tablet was found that was written in Reformed Egyptian, there are several artifacts resembling exactly the Menorah, and they have also found a tablet inscribed with the Ten Commandments and a picture of Moses. Also, the mitochondrial DNA taken from both the remains of those cultures and from present day Native Americans, have a large amount of haplogroup X. Mitochondrial DNA is DNA from the mitochondria that doesn't mutate and is passed from mother to daughter. This specific branch of haplogroup X (X2 specifically) has been traced back to Jerusalem, specifically the hills of Galilee.

They both build burial mounds
Adena were there first (800 B.C. - 200 A.D.). The Hopewell culture came later but overlapped with the Adena (200 B.C. - 400/500 A.D.). Most theories hold that the two intermixed peacefully, and the Hopewell culture was an elaboration and extension of the Adena mound-building culture. Thus the Hopewell art, burial ceremonies, etc were more flamboyant than that of the earlier and more primitive Adena.
